6 Claims.

This invention relates to improvements in display carton construction and it has particular reference to the formation of foldable paper board cartons with an easel for supporting the carton in an inclined position so as to more advantageously display the content of the carton.

The main objects of the invention are to provide a carton with an easel construction which may be easily set up when the boX is set up and which easel construction will firmly support the carton in the desired inclined position for the purpose of displaying the content of the carton; to provide an easel construction of the character indicated which may be quickly and easily collapsed to flat condition to facilitate packaging and storing of the filled container; and in general it is the object of the invention to provide an improved display carton of the character indicated.

Other objects and advantages of the invention will be understood by reference to the following specification and accompanying drawings (two sheets) wherein there is disclosed a display carton embodying a selected form of the invention.

In the drawings:

Fig. 1 is a perspective illustrating the improved carton in display position;

Fig. 2 is a perspective bottom view of the carton showing its easel construction partially folded to flattened position;

Fig. 3 is a fragmentary perspective corresponding to a portion of Fig. 2 but showing the easel structure completely folded to flattened condition;

Fig. 4 is a longitudinal section through the improved carton with its easel extended as in Fig. 1 and the cover of the carton closed;

Fig. 5 is a section on the line 5-5 of Fig. 4;

and

Fig. 6 is a plan of a blank employed in forming the carton.

The carton herein disclosed embodies a receptacle having side walls l0 and II, front and back walls l2 and I3, respectively, and a bottom wall M. The receptacle is formed from the blank structure shown in Figure 6; it is a one-piece blank of suitable paper board provided with suitable fold lines indicated at F and slits indicated at S, which serve to divide the blank into various panels to form the said walls of the receptacle. The side walls In and and the bottom wall |4 constitute single panel sections of the blank but the front and back walls I2 and I3 comprise a plurality of panels or sections which are folded into mutually overlapping relation to form the multi-ply front and back walls.

In folding the blank to form the receptacle, the side walls I0 and II are first folded to right-angular relation to the bottom wall l4. As shown in Figure 6, the side wall sections are connected to the bottom wall section through intervening, triangular panel sections 2|, 22, 23 and 24, suitable fold lines serving to separate said triangular sections from each other and from the respective sidewall and bottom panels.

In setting up the receptacle, the triangular sections 22 and 23 are first folded downwardly from the adjacent side edges of the bottom panel l4 and the triangular sections 2| and 24 are then folded upwardly, the side wall sections 10 and II remaining in their normal, co-planar relation to said sections 2| and 24. The arrangement is such that the bottom edges of the panel sections l0 and I will, when folded as explained, coincide with the respectively adjacent side edges of the bottom panel M. The triangular sections 2| and The front wall |2 comprises panel sections l5 and I6 and end flaps H and I8. The end flaps;

IT and I8 are eparated by slitting from the adjacent ends of the sections Hi and I6 and they are foldable into mutually overlapping and rightangular relation to the respective side walls l0 and II and the sections |5'and l5 are foldable upwardly over the outside of the overlapping flaps l1 and I8 and then downwardly over the inside thereof. The section I6 is preferably provided with a tongue H! which is adapted to enter a slit 20 provided in the bottom Wall M to thereby lock the sections l5 and IS in the described folded, front wall forming position. Said panel sections l5 and I6 embrace portions of the flaps l1 and |8 and thereby serve to maintain the same in folded, front wall forming position.

The back wall |3 of the container comprises a panel or section 21 extending from the rear end of the bottom wall section l4, and fiapsor f wings 28 and 29 which extend from the rear ends of the ide walls It] and II, respectively. The panel 21 is adapted to be folded upwardly to substantially right-angular relation to the bottom wall and the height of the back panel 21 preferably is substantially the same as the height of the side walls I and H. The flaps or wings 2B and 29 are then folded inwardly from the respective side walls I0 and II into mutually overlapping relation and into overlapping relation to the back wall panel 21 on the outside thereof. The wings 28 and 29 may advantageously be provided with suitable interlocking means such as a hook and slit arrangement as illustrated.

The back Wall forming wings 28 and 2 9 are provided with depending extensions 30 and 3|, respectively, said extensions also constituting endwise extensions from the triangular sections 2| and 24, respectively. When the Lrear wall forming flaps 28 and 29 are folded and locked in said back wall forming position, th extensions 30 and 3| thereof constitute a rear section of the easel structure which embodies the triangular sections 2| and 22 at one side of Ithe receptacle, the triangular sections 23 and 2-4 at the other side, and said extensions 30 and 31 at the rear.

As indicated in Figure .6, the rearward endportions of the easel forming sections 2| and 24 are separated from each other by a short slit line and the outer section 2| is provided with .a diagonally extending slit line connecting the inner end of the slit S with the rear lower corner of the side wall section It]. Similarly, the outer triangular section 24 of the easel structure .ontheother side of the receptacle has its rearward portion separated from the rearward portion of the inner easel section '23 by a short slit line 5 and said outer section 24 is provided with a triangular slit line extending from the inner end of said slit line S to the lower rear corner of the ide wall H.

The short slit lines S separating the rearward portions of the easel forming sections and the diagonal fold lines just described serve to permit the easel structure to be collapsed into a flat, folded position on the bottom of the container substantially as shown in Figures 2 and '3. By reference to the :said figures it will be observed that the rear ends of the inner easel sections 22 and 23 are free of connection with the adjacent rear section 3| of the easel structureso that said easel sections 22 and 23 may readily be folded inwardly toward flat position on the bottom wall of the receptacle.

The outer sections 2| and .24, :being integrally connected at their lower edges to said inner sections 22 and 23, will of course be caused to follow said inner sections inwardly and such folding .of the outer sections is permitted by reason of the said diagonal fold lines which permit the triangular end portion 32 and 313, respectively, of said outer sections 2| and 24 to be folded into face to face, overlapping relation to the respec-- tively adjacent portions of the easel sections 2| and 24. The rear sections 30 and 3| of the easel structure are mutually automatically folded flat position on the bottom of the container substantially as hown in Figure 3.

The easel structure may thus be readily collapsed or folded to inoperative position for shipment and storage purposes and it may be quickly and easily set up to operative position merely by unfolding the rear portion comprising the :seo-

tions 30 and 3|. When suchrear portion is unfolded, the side sections of the easel structure will be automatically unfolded because of the presence of the connecting portions 32 and 33 between theends of said rear portion of the easel structure and the respective side portions thereof.

The easel structure, being continuous around the sides and rear of the container, is quite rigid when set up and serves to very effectively support the container in an inclined display position. It will be observed that manipulation of the easel structure does not require the insertion of tongues or other parts of the easel structure into openings for locking purposes, nor careful manipulation to insure interengagement of any unconnected parts.

The receptacle may be provided with a cover structure comprising a panel or section 34 which extends from-the'upper edge of the rear wall sec- "tion 21 and is adapted to be folded at said edge into substantially parallel relation to the bottom section M. The panel 34 is of such size that it extends over the entire top of the container, overlying the in-turned top flanges and 26 was to be thereby supported.

The front of the container .is recessed as shown in Figure 1 as the result of the illustrated formation of the front forming flaps H and I8. The front of the container may be closed by providing the cover section 34 with a flap extension ;35.. The flap extension 35 is adapted to be folded downwardly from the cover structure 341as shown in Figure 4. Said front closing section 35 is preferably so shaped that its upper portion overlies the open upper portion of the front wall |2 of the container and its lower portion constitutes a tongue adapted to be inserted between the vsides of the opening in the front wall to the inside of the front wall structure substantially as shown in Figure e. Said cover structure may also be provided with slitting S and fold lines F which permit the cover to be folded uponitself to form a display panel adapted to extend upwardlyfnom the back of the container as shown in Figure 1. When so positioned, the free end portion of the cover structure may be inserted in the rear of the container bet-ween the rear ends of the flanges 2-5 and 2.6 and the back wall .21 and between the back wall 2! and the content of the package to thereby retain the cover structure .in folded, upwardly extending, display panel position.

Change in the described structure may be made without departing from the spirit of :the invention, the scope of which should .be determined by reference to the following claims, the same being construed as broadly as possible, consistent with the state of the art.
